本地npm依赖性“不包含package.json文件”。在docker build中，但是在npm start上运行良好

本文介绍了本地npm依赖性“不包含package.json文件”。在docker build中，但是在npm start上运行良好的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有一个本地正在使用的npm模块，它是客户端应用程序中的依赖项。

I have an npm module I'm working on locally that is a dependency in a client app.

目录结构基本上如下：

/app
  /client
    /src
      App.js
    package.json
    Dockerfile.dev
  /shared
    /contexts
      package.json
      test.js
    /hooks

我的 package.json 如下：

{
  "name": "web",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "contexts": "file:../shared/contexts",
    "react": "^16.10.2",
    "react-dom": "^16.10.2",
    "react-scripts": "3.2.0"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

将以下内容导入 client / src / App。 js ：

import { testImport } from 'contexts/test';

当我运行 npm start 时按预期工作。

Works as expected when I run npm start.

我遇到的问题与运行有关：

The issue I'm running into is with running:

docker build -t sockpuppet/testapp -f Dockerfile.dev .

失败，并出现错误：

npm ERR! Could not install from "../shared/contexts" as it does not contain a package.json file.

这是Dockerfile.dev

Here is he Dockerfile.dev

FROM node:alpine
WORKDIR '/app'
COPY ./package.json ./
RUN npm install
COPY . .
CMD ["npm", "run", "start"]

我应该如何

还要在 COPY 中添加如下内容： / shared 进入映像会生成 COPY失败：构建上下文之外的禁止路径：../shared/contexts（）错误：

Also, adding something like the following to COPY the /shared into the image generates a COPY failed: Forbidden path outside the build context: ../shared/contexts () error:

COPY ../shared ./

推荐答案

好的，这可行。我将 Dockerfile.dev 更改为以下内容：

Ok, this works. I changed my Dockerfile.dev to the following:

FROM node:alpine
WORKDIR '/app'
COPY ./shared /shared
COPY ./web /app
RUN npm install
CMD ["npm", "run", "start"]

从基础项目目录（其中 / shared 和 / web 驻留），我运行：

From the base project directory (where /shared and /web reside), I run:

docker build -t sockpuppet/client -f ./web/Dockerfile.dev .
